The HP ProLiant SL390s G7 Server is part of a new family, HP ProLiant SL6500 Scalable System, of HP server solutions optimized for scale-out customers to greatly reduce costs, maximize power efficiency, by sharing power supplies and fans, and maintain total flexibility.

The SL390s G7 consists of three different server trays, each with their own benefits. The 1U half width tray is designed for compute density, and the 2U and 4U half width trays are designed for GPU density, support is up to 3 GPUs in the 2U and 8 GPUs in the 4U tray. They each use the same system board and go into the 4U HP ProLiant s6500 Chassis. The SL390s G7 is a two socket Intel server with 12 DDR3 DIMM sockets, two 1 Gb Ethernet ports, one 10 Gb Ethernet port (SFP+) and an option on board Infiniband port (QSFP).

The s6500 Chassis is 4U and can accommodate up to eight half width servers, all individually serviceable. Also, it can support up to four power supplies, non redundant or hot plug redundant fans.
